” A Tesla Model S, which has 18 moving parts, one hundred times fewer than a combustion engine car. “Maintenance is essentially zero,” says Stanford University economist Tony Seba. “That is why Tesla is offering infinite-mile warranties. You can drive it to the moon and back and they will still warranty it.”

No more petrol or diesel cars, buses, or trucks will be sold anywhere in the world within eight years. The entire market for land transport will switch to electrification, leading to a collapse of oil prices and the demise of the petroleum industry as we have known it for a century.

This is the futuristic forecast by Stanford University economist Tony Seba. The professor’s report, with the deceptively bland title Rethinking Transportation 2020-2030, has gone viral in green circles and is causing spasms of anxiety in the established industries.

Mr Seba’s premise is that people will stop driving altogether. They will switch en masse to self-drive electric vehicles (EVs) that are 10 times cheaper to run than fossil-based cars, with a near-zero marginal cost of fuel and an expected lifespan of 1 million miles (1.6 million kilometres).

Only nostalgics will cling to the old habit of car ownership. The rest will adapt to vehicles on demand. It will become harder to find a petrol station, spares, or anybody to fix the 2000 moving parts that bedevil the internal combustion engine. Dealers will disappear by 2024.

Cities will ban human drivers once the data confirms how dangerous they can be behind a wheel. This will spread to suburbs, and then beyond. There will be a “mass stranding of existing vehicles”. The value of second-hard cars will plunge. You will have to pay to dispose of your old vehicle.

It is a twin “death spiral” for big oil and big autos, with ugly implications for some big companies on the London Stock Exchange unless they adapt in time.

The long-term price of crude will fall to $US25 a barrel. Most forms of shale and deep-water drilling will no longer be viable. Assets will be stranded. Scotland will forfeit any North Sea bonanza. Russia, Saudi Arabia, Nigeria, and Venezuela will be in trouble.

It is an existential threat to Ford, General Motors, and the German car industry. They will face a choice between manufacturing EVs in a brutal low-profit market, or reinventing themselves a self-drive service companies, variants of Uber and Lyft.

They are in the wrong business. The next generation of cars will be “computers on wheels”. Google, Apple, and Foxconn have the disruptive edge, and are going in for the kill. Silicon Valley is where the auto action is, not Detroit, Wolfsburg, or Toyota City.

The shift, according to Mr Seba, is driven by technology, not climate policies. Market forces are bringing it about with a speed and ferocity that governments could never hope to achieve.

“We are on the cusp of one of the fastest, deepest, most consequential disruptions of transportation in history,” Mr Seba said. “Internal combustion engine vehicles will enter a vicious cycle of increasing costs.”

The “tipping point” will arrive over the next two to three years as EV battery ranges surpass 200 miles and electric car prices in the US drop to $US30,000 ($40,600). By 2022, the low-end models will be down to $US20,000. After that, the avalanche will sweep all before it.

“What the cost curve says is that by 2025 all new vehicles will be electric, all new buses, all new cars, all new tractors, all new vans, anything that moves on wheels will be electric, globally,” Mr Seba said.

“Global oil demand will peak at 100 million barrels per day by 2020, dropping to 70 million by 2030.” There will be oil demand for use in the chemical industries, and for aviation, though Nasa and Boeing are working on hybrid-electric aircraft for short-haul passenger flights.

Mr Seba said the residual stock of fossil-based vehicles will take time to clear, but 95 per cent of the miles driven by 2030 in the US will be in autonomous EVs for reasons of costs, convenience, and efficiency. Oil use for road transport will crash from 8 million barrels a day to 1 million.

Insurance costs to fall by 90 per cent

The cost per mile for EVs will be 6.8 cents, rendering petrol cars obsolete. Insurance costs will fall by 90 per cent. The average American household will save $US5600 per year by making the switch. The US government will lose $50 billion a year in fuel taxes. Britain’s exchequer will be hit at the same rate.

“Our research and modelling indicate that the $10 trillion annual revenues in the existing vehicle and oil supply chains will shrink dramatically,” Mr Seba said.

“Certain high-cost countries, companies, and fields will see their oil production entirely wiped out. Exxon-Mobil, Shell and BP could see 40 per cent to 50 per cent of their assets become stranded,” the report said.

These are all large claims, though familiar those on the cutting edge of energy technology. While the professor’s timing may be off by a few years, there is little doubt about the general direction.

India is drawing up plans to phase out all petrol and diesel cars by 2032, leap-frogging China in an electrification race across Asia. The brains trust of Prime Minister Narendra Modi has called for a mix of subsidies, car-pooling, and caps on fossil-based cars. The goal is to cut pollution and break reliance on imported oil, but markets will pick up the baton quickly once the process starts.

China is moving in parallel, pushing for 7 million electric vehicles by 2025, enforced by a minimum quota for “new energy” vehicles that shifts the burden for the switch onto manufacturers. “The trend is irreversible,” said Wang Chuanfu, head of the Chinese electric car producer BYD, backed by Warren Buffett’s Berkshire Hathaway.

At the same time, global shipping rules are clamping down on dirty high-sulphur oil used in the cargo trade, a move that may lead to widespread use of liquefied natural gas for ship fuel.

This is all happening much faster than Saudi Arabia and Opec had assumed. The cartel’s World Oil Outlook last year dismissed electric vehicles as a fringe curiosity that would make little difference to ever-rising global demand for oil.

It predicted a jump in crude consumption by a further 16.4 million barrels a day to 109 million by 2040, with India increasingly taking over from China as growing market. The cartel said fossils will still make up 77 per cent of global energy use, much like today. It implicitly treated the Paris agreement on climate targets as empty rhetoric.

Whether Opec believes its own claims is doubtful. Saudi Arabia’s actions suggest otherwise. The kingdom is hedging its bets by selling off chunks of the state oil giant Saudi Aramco to fund diversification away from oil.

Opec, Russia, and the oil-exporting states are now caught in a squeeze and will probably be forced to extend output caps into 2018 to stop prices falling. Shale fracking in the US is now so efficient, and rebounding so fast, that it may cap oil prices in a range of $US45 to $US55 until the end of the decade. By then the historic window will be closing.

Experts will argue over Mr Seba’s claims. His broad point is that multiple technological trends are combining in a perfect storm. The simplicity of the EV model is breath-taking. The Tesla S has 18 moving parts, one hundred times fewer than a combustion engine car. “Maintenance is essentially zero. That is why Tesla is offering infinite-mile warranties. You can drive it to the moon and back and they will still warranty it,” Mr Seba said.

Self-drive “vehicles on demand” will be running at much higher levels of daily use than today’s cars and will last for 500,000 to 1 million miles each.

It has long been known that EVs are four times more efficient than petrol or diesel cars, which lose 80 per cent of their power in heat. What changes the equation is the advent of EV models with the acceleration and performance of a Lamborghini costing five or 10 times less to buy, and at least 10 times less to run.

“The electric drive-train is so much more powerful. The gasoline and diesel cars cannot possibly compete,” Mr Seba said. The parallel is what happened to film cameras – and to Kodak – once digital rivals hit the market. It was swift and brutal. “You can’t compete with zero marginal costs,” he said.

The effect is not confined to cars. Trucks will switch in tandem. Over 70 per cent of US haulage routes are already within battery range, and batteries are getting better each year.

EVs will increase US electricity demand by 18 per cent, but that does not imply the need for more capacity. They will draw power at times of peak supply and release it during peak demand. They are themselves a storage reservoir, helping to smooth the effects of intermittent solar and wind, and to absorb excess base-load from power plants.

Mark Carney, the Governor of the Bank England and chairman of Basel’s Financial Stability Board, has repeatedly warned that fossil energy companies are booking assets that can never be burnt under the Paris agreement.

He pointed out last year that it took only a small shift in global demand for coal to bankrupt three of the four largest coal-mining companies in short order. Other seemingly entrenched sectors could be just as vulnerable. He warned of a “Minsky moment”, if we do not prepare in time, where the energy revolution moves so fast that it precipitates a global financial crisis.

The crunch may be coming even sooner than he thought. The Basel Board may have to add the car industry to the mix. There will be losers. Whole countries will spin into crisis. The world’s geopolitical order will be reshaped almost overnight. But humanity as a whole should enjoy an enormous welfare gain.
